Ash dieback disease

Ash dieback is a disease of Ash trees caused by a disease called Chalara fraxinea.The disease causes leaf loss and crown dieback in affected trees and it may lead to tree death.

See below for some precautionary advice from the Forestry Commission:

The risk of visitors spreading the disease is very small and we are not closing forests or advising owners of infected sites to do so. We do ask that if you are visiting an infected or suspected wood, please take some simple precautions:

do not remove any plant material (firewood, sticks, leaves or cuttings) from the woodland;

where possible, before leaving the woodland, clean soil, mud, leaves and other plant material from footwear, clothing, dogs, horses, the wheels and tyres of bicycles, baby buggies, carriages and other vehicles, and remove any leaves which are sticking to your car;

This is just one of a number of threats that our city trees face. We know that many of our trees in UK cities were planted in the Victorian era and cannot last forever. Will you help us to plant new trees this year?
